Loading google.vim indent file in Vim

I am attempting to use the google.vim (and on vim.org) indent style for my c++ project, but I can't seem to load it. I installed

google.vim

using vundle and opened up a cpp file and noticed that my tabstops, shiftwidths, etc did not change. If you set global ts and sw parameters, are they not overwritten? How do you force a certain indention when editing a file in vim? I want everything in my vimrc file to be overwritten by the google.vim file when I edit a cpp file.

Running the

:filetype

command in vim reveals this information:

detection:ON plugin:ON indent:ON

The bottom line is that I don't understand how to tell vim to use my google.vim file located under ~/.vim/vundle/google.vim/indent/google.vim. From what I have read, vim detects that filetype of your current file and uses the appropriate .vim file for syntax and indentation. So would I then have to rename my google.vim file to something like cpp.vim?

In most cases I like to use a tabstop of 3 and a shiftwidth of 3, so I set these in my .vimrc file. However, when I edit a cpp file, I want all my settings to be changed from what I have set globally to what the google.vim file sets.
